Updated: December 13, 2007

Applies To: Windows Server 2008

BITS (Background Intelligent Transfer Service) Server limits the number of upload sessions that can exist concurrently for a user. If the number of sessions for a user is more than this limit, Task Scheduler is triggered to perform the BITS Cleanup task. Task Scheduler scans the directory and keeps the first number of sessions it encounters. When the number of encountered sessions equals the configured limit, the rest are deleted. By default, Task Scheduler is set to clean up every 12 hours, an interval that can be configured by the administrator.
